In the classic words of the Geto Boys, "This year Halloween fell on a weekend..."
See who all went trick-or-treatin' (and hit up the Halloween parties) inside....
Ok. The Game won Halloween 2015.
The rapper dressed up as "Classic Man" rapper Jidenna last night for the Casamigos Tequila Halloween Party at a private residence in LA. And totally nailed it! He committed to the look wholeheartedly -- dyed his hair auburn, made sure that swirl part was just right, and his umpteen piece suit and cane were on point. Yasss Game!
Russell Simmons was also at the party dressed as his brother Rev Run as usual.
Serena Williams came through to the party as an 80's Prom Queen.
Tracey Edmonds rocked her hot pants and thigh high boots to become a racer girl.
Holly Robinson Peete and husband Rodney Peete served throwback realness on their way to the party.
The ladies on "The Real" went for a fantasy-like theme....
It appears “The Real” ladies were all dressed up as “good” characters. Tamera Mowry-Housley transformed into Mary Poppins, Loni Love dressed up as Glinda the Good Witch of the North, Jeannie Mai went as Jeannie of “I Dream of Jeannie (of course), Adrienne Bailon dressed up as Wonder Woman and Tamar Braxton was Tinkerbell.
And look who dropped in…..
Tamera's baby girl Ariah Housley got dressed up for her very first Halloween. Too cute!
Shanola Hampton (from Showtime's "Shameless") also stopped by looking fab to share Halloween photos, stories and last minute make-up/prop tips.
Over at the White House yesterday, President and First Lady Obama welcomed the cutest trick-or-treaters which were made up of hundreds of local schoolchildren and children from military families.
The First Couple didn't dress up in costume, but we're loving their fall gear.
As for who won the costume contest:
Reports say Obama gushed over baby Pope Francis! Hands down the cutest outfit of the kiddies there.
The Obamas cracked jokes with parents as they handed out the White House's own Halloween cookies, M&Ms, fruit bars, kettle corn, candies and baseball cards featuring their dogs Bo and Sunny.
Back in the Oval Office yesterday, Prez O hung out with Ella Rhodes, pictured in her elephant Halloween costume. Ella is the daughter of Ben Rhodes, deputy national security advisor. *Squeals* So cute!
Happy Halloween all! Check out our celeb-filled Halloween gallery below!
